Thisy invention relates topull'ers and more wardly vbetween these arms forces these lowparticularly to adevice of this character for er ends apart. This stem at its lower end extracting tliebearing cups of roller bearis splned to the-stein '14 of the pulling ings from the hubs of automobile wheels. screw and atits upper end is threaded, as

A An important ob ect of the invention is to indicated at 24. This threaded upper end 60 provide asd'evice of this character which is projects above vthe upper end of the stem readily engaged with both the wheel and 14 and has mounted'thereon a lever nut 25, cup and which will exert a steady and powby means of which it lmay bev drawn uperful pull upon the cup to remove the same., wardly. v 1o A Jfurther object of the invention is the' It will be obvious that by positioning the 65 provision in a construction of this character hooks 18 against the" cup bottom and movof positive means for preventing disengageing the stein 22 upwardly, the wedge 23 will ment of the pulling apparatus -from the cup engage these hooks and prevent their withduring the pulling operation. drawal from the cup bottom, so that there 1.5 These and other objects I attain by the is no danger of the puller slipping in opera- 70 construction shown in the accompanying tion. With the hooks locked against disendrawings, wherein for the purpose of illusgagement, pressure may be applied to the tration is shown a preferred embodiment of cup by rotation of the lever nut 20. my invention and wherein Since the construction hereinbefore set vFigure 1 is a side elevation partially in forth is capable of a certain range of change 75 section of a puller constructed in accordance and modification without materially departwith my invention showing the 'same applied ing from the spirit of the invention, I do to remove the bearing cup of an automobile not limit myself to such specific structure wheel; except as hereinafter claimed. i Figure 2 is a plan view of the puller; I claim :-4 l

In a puller for removing bearing cups Figure 1. from the hubs of vehicle wheels andthe like, Referring now more particularly to the a standard having an openin formed theredrawings, the numeral 10 designates a subthrough and having legs or engagement stantially U-shaped frame, the arms 11 of against the wheel hub, a pulli/ng .Screw d- 85 which are adapted to engage against an auto rected through theopening of the standard wheel hub I-I when the cross bar 12 thereof and having at its lower end pairs of arms is opposed to the axis of this hub. This cross one of which has engagement with a leg of bar has an opening 13 formed therein axialthe standard preventingrelative rotation of 35 1y aligning with the hub through which is thescrew and standard, -dogs pivoted be- 9o directed the threaded shank 14 of a pulling tween the arms of each pair and having at screw, the inner or hub confronting end of their free ends hooks for engagement with which has diametrically opposed pairs of the bearing cup andmeans for orcibly spaced arms 15. One of these arms 15 is maintaining said dogs in separatedrelation. elongated, so that it engages an arm 11, as 2. In a puller for removing bearing cups '95 indicated at 16, so that relative rotation of from' the hubs of vehicle wheels and the like, the pulling screw and the U-shapedl standard a standard having an 'openin formed there-v is prevented. Pivoted between each pair' ofthrough and having legs or' engagement arms is a dog 17 the lower end of which is against the wheel hub, a pulling Screw diin the form of an outwardly facing hook -rected through the opening of theA standard 100 adapted to engage the inner face of thebotand having at its lower end pairs of arms tom of a bearing cup 19. vThe stem 14 above one of which has engagement with a .leg of vthe cross bar h as mounted thereon a lever the standard preventing relative rotation of nut 20, whereby it maybe drawn through the screw and standard, dogs pivoted the opening 13, and between this lever nut` tween the arms of. each pair and havmg at 1054 and the cross bar 12, a thrust washer 2 1 is their freeends hoolrs for engagementwith preferably disposed. The'stem 14 is tubular the bearing cup, said pullingA screw `being and has directed therethrough the stem 22 of tubular, a wedge positioned between the free a wedge 23, which extends between the lower .ends of said dogs and havin a -stem extendi ends of the arms 17 and when moved uping through and means attl e-upper end of 110 the wedge stem and engaging the pulling screw for drawing the wedge stem upwardly through the pulling screw.
